Bar Turning Machine from Alankar Udhyog is defined by its ability to provide high-precision finishing and 'peeling' for metal rods. As a leading manufacturer based in Vadodara, Gujarat, Alankar Udhyog designs these machines to convert black bars into bright, finished shafts by removing surface defects and achieving tight tolerances. Key Selection Factors The Best-Seller (Model A-2): Often cited as the most versatile unit, the Model A-2 is ideal for workshops handling standard industrial shafts. It balances a 100 mm capacity with high spindle torque, making it effective for both mild steel and stainless steel. Precision Specialist (Model A-1): If your workflow focuses on smaller components like pump shafts or fasteners, the Model A-1 offers higher RPMs (up to 1500) which helps in achieving a finer surface finish on smaller diameters. Industrial Powerhouse (Model A-4): For large-scale manufacturing of heavy rods, the Model A-4 features a massive 750 mm chuck size and a robust 30 HP spindle motor to handle maximum material removal on bars up to 200 mm. Essential Technical Facts Design: These machines typically utilize a vertical layout or a heavy-duty horizontal bed made of high-quality cast iron to dampen vibrations, which is critical for maintaining accuracy. Cutter Head: The machines feature a rotating cutter head with multiple tool pockets (often 3-4) that travel longitudinally along the stationary bar, ensuring the rod remains straight during the turning process. Material Compatibility: While primarily used for Mild Steel (MS) and Stainless Steel (SS), they are also effective for copper, brass, and aluminum rods. Recommendation: If you are looking for a 'workhorse' that covers the most common bar sizes in the industry, the Model A-2 is the superior choice. However, for specialized heavy engineering, the Model A-4 is the only unit in their lineup capable of handling 200 mm diameters.
